That’s heartbreaking Tim. I feel for you brother.
Parenting is about safety. Children need a safe place to explore the world, so that when they become adults, they can live independently, in safe ways. (Notice I didn’t say “perfect”. “Perfect” is a fantasy. I said “safe”.)
There’s a lot of ways that you can be her father in safe ways. Working your sobriety, with a program (for example, www.NA.org or one of the programs here: Resources for our recovery), and showing up to supervised visits sober, is safe. If you do that, you are being her father and keeping her safe.
You are capable of doing this. You are capable of providing a safe space for your daughter to grow up. And when you do that, you are being her father. It doesn’t matter where or how often you see her physically, just as long as she is safe. (Edit to add: think of it like a soldier on deployment. Some soldiers go months or even more than a year between visits with their kids. Yet no one says they’re not a parent. You are the same. You are fighting a war against addiction. Addiction is the enemy. It will take every ounce of your strength. But it does not mean you’re not a father. You can fight and win this war, and still be a father.)
Find a program and work it. Be sincere and be ready to get uncomfortable. Remember that no one owes you anything. You’re in this because it’s the right thing to do and you are choosing to do the right thing. Whatever happens after that, you can’t predict - just take it one day at a time, one hour at a time.
Sending you love and prayers brother. You’re a good person. You deserve a safe, sober life where you can be your full self.
